Academic Performance Evaluation of Students (apes);
Ubiquitous System Analyzed (usa);
Letter-Grading-System is Crude-and-Rude;
Raw Scores to Letter Grades to GPA, is unfair, by design;

truth lies exposed (the problem is not just Grade-Inflation);
Chaotic System Biased Information Loss/Corruption (CSBILC);
Chaotic System Biased Amplification or Attenuation of Differentials (CSBAAD),
Chaotic System Biased Suppression or Expression of Differentials (CSBSED),
Chaotic System Biased Relative Rank Inversion (CSBRRI),

: discovered (kph.2002.08.08);

Contraction-Expansion Mapping, Quantization;

Students Academic Performance Evaluation System (SAPES), proposed;
Student Academic Performance Index (SAPI), defined;

Numerical Scores/Marks is the best choice,
for a true representation of a measure for the
